HAIR CLIPPER.

Application and September so, 1925,8er1a1 mi. same. Renewed time 1, 1a.

vide a power operated hair clipper w ich will be rovided with clipperelements at its opposite ends, and which will be adapted to receiveseparate operating means for operating the separate clipper elements.

A further object of the invent on 1s to provide a power operated haircllpper whlch will have its casmg or housing so constructed that it willreadily adapt itself to practically any angle when cutting halr.

A still further object of the invention is to provide a power operatedhalr cllpper which will be highly efiicient in use and quite ine nsiveto manufacture.

Other 0 jects will appear as the descrlption proceeds. o

In the accompanying drawmgs which constitute a part of my application,

Fi per s owing the interior construction thereof in dotted lines;

Figure 7 is a side elevation of a single clipper element power operatedhair clipper.

Figure 8 is aplan of a modification in which the clipping units arelaterally offset from each other, and

Figure 9 is a side elevation of the same.

Like characters of reference are used through the followingspecification and the re 1 is a plan v1ew of my hair clipstantiallyflat, while the lower portion there- 69 of is flat at its centralportion and is provided with the concave portions-3 at either side ofthe central portion. Adjacent the concave portions 3 are the downwardlyextending convex surfaces 4 which terminate in an upwardly direction atthe outer ends of the said casing. The outer ends of said casing 1 areprovided with notches 5 into which are adapted to seat the cutter bars 6and 7 whichhave formed thereon coarse and .fine teeth respectively. Setscrews 8 are adapted to hold the cutter bars in fixed position at theends of the casing 1.

Air chambers 9 are formed within the convex portions 4-of the casing 1and are provided with the inner walls 10 which form the bottoms of theoil chambers 11, the same being formed at the opposite ends of saidcasing.

Tension posts 12 are secured at the oppo- 30 site ends of the casing 1and extend up vertically therefrom. The cutter plates 13 are adapted toseat on the cutter bars 6 and 7 and to reciprocate thereon. The saidcutter plates 13 are provided with the inset bearing grooves 14 intowhich are adapted to be placed the substantially T-shaped outer ends ofthe oscillating levers 15 which are pivoted on the tensioning posts 12.

Bosses 16 are provided adjacent the inner W ends of the clipper casing 1and have mount-- ed thereon the worm wheels 17. which are mounted on thestub shafts 18, the same being deta'chably secured in said bosses. The

pins 19 are positioned in thewormrwheels 17 and extend upwardlytherefrom and carry the slidable blocks 20, which are slidable in thelongitudinally extending slots 21 in the oscillating levers 15. Theupper and open sides of the oil chambers 11 are provided with the coverplates 22. which serve to retain the oil in said chambers. The capplates 23 are adapted to extend over the tensioning screws or studs 12and have their outer ends seated on the cutter plates 13 and their innerends on the cover plates 22.

Washers 24 are placed overthe tensioning screws 12 after which the nuts25 are tight ened down on said screws until the desired tension issecured.

The opposite sides of the casing l are provided with the boxes 26 whichare hollow and are adapted to receive the flexible conduits 27, the samebeing mounted in the bushings 28 between which are positioned the wormgears 29 which mesh with the worm-wheels 17. The reciprocating pins 30are normally teusioned by means of the springs 31 and they are adaptedto seat in the annular grooves 32 in the cables 27.

The same construction may readily be used on a single or double endedclipper, the only difference in construction being. that in the case ofthe single clipper gripping extensions or holders 33 are formed on theoppo site sides of the casing 1, and the flexible cable 27 enters intothe casing 1 from the inner end of the said clipper. In both the singleand double ended clippers air chambers are also formed at the inner endof the oil chambers as at 34. In order to close the socket or bore notin use a removable cap 35 is fitted on to the outer end of the. socket.

It has been heretofore impossible to keep the power driven hair clippersfrom becoming overheated due to the continual use, but I find that byproviding air chambers and positioning them as I do that the clipperswill not heat up even when used for a long period of time.

It will be understood that I do not intend to limit myself to thespecific construction of the hair clippers, for it is obvious that manyminor changes in detail of Construotion may be resorted to withoutdeparture from the spirit of the invention.

One of my special features is the forming of longitudinally extendinggrooves 36 on the lower surface of the convex portions 4 of the casing1, and registering grooves of corrgespornding width on the cutter barsas shown Having thus described my invention, what I claim as new anddesire to secure by Letters Patent of the United States, is:
